vigil/ffii@ h To all whom it may concern: f

Be it known that I, OHARLESO. BIRNEY, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Car-Window Curtain-Rods, of whichy the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. i

My invention relates to a car window curtain rod, my object being to construct a simple, inexpensive curtain rod particularly adapted for the curtains of car windows, and the ends ofthe curtain rod being provided rollers which operate inthe curtain grooves formed in the side faces of the window posts, said yielding members being provided with retaining device, which prevents the parts carried by the ends of the rods from being withdrawn from the curtain grooves, and thus the lower end of the curtain is always maintained in proper position.

A further object of my invention is to equip the ends of the curtain rod with yielding members, there being adjustable connections between said yielding members and the ends of the rod whereby the members may be moved inward or outward to varyV the friction between the rollers and the faces of the window posts.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:-

Figure 1 is an elevation of the lower end of a car window curtain equipped with a rod of my improved construction; Fig. 2 is. an enlarged horizontal section taken approximately on the line 2-2 of Fig. 1 g Fig. 3 is a vertical section taken on the line 3--3 of Fig. 2; Fig. 4-is a horizontalsection similar to'Fig. 2, and showing-a modiiied form of the curtain rod; Fig. 5 is a vertical sectionrtaken api proximately on the line 5-,5 of Fig. 4; and Fig. 6 is a detail view illustrating a modified form of construction of the curtain groove.

Referring by numerals to the accompanying drawings: l designates the window posts of the car, which are of the usual construction, and provided on their inner faces with j Specification of Letters Patent. Application led Apriljll, 1908. Serial No. 426,616.

CAR-WINDOW CURTAIN-Ron.

the postmolding 2, and formed in the rear faces of the projectingportions of said molding are vertically disposed grooves 3.

Fixed on the side faces of the window posts are the vertically disposed parting strips 4, and formed in the faces thereof, immediately adjacent the projecting portions of the moldingl2, are grooves 5, which are directly opposite the grooves 3, and thus a curtain groove 6 is formed, which groove is T-shaped in cross section.

The window sash 7, of ordinary construction, operates in the usual manner between the window posts 1 to the rear of the parting strips 4. i

8 designates the curtain, of usual form, and arranged at the lower end thereof is the curtain rod 9, which is in the form of a tube,

with its ends interiorly screw threaded, as designated by 10.

Screw seated in the threaded ends of the tubular curtain rod are pins 11, in the outer portions of which are formed the grooves 12. Arranged on the projecting port-ion of each pin is a socket 13, and passing therethrough is a set screw 14, the inner end of which enters the corresponding groove 12, thereby Vmaking a swivel connection between each pin 11. and socket 13.`

Formed integral with each socket isa vertically disposed segmental spring. 15, the ends 'of which are provided with pairs of lears 16, which normally occupy the main portion of the T-shaped curtain groove, and journaled on pins 17, passing through each pair of ears, are small rollers 18, which bear againstl the faces of the window posts. 1 in the curtain grooves 6;

Loos'ely arranged on each of thepins 17 and between the ears 16 and rollers 18 are plates or washers 19, and projecting outwardtherefrom into the grooves 3 and 5 are pins 20.. These washers 19 and pins 20 form hooks which are pivotally arranged on the ends of the springs 15, and which provide simple Ameansfor preventing the ends of said springs'from becoming accidentally disengaged from the curtain grooves.

When a curtain equipped with my improved rod is raised or lowered in the proper manner, the rollers 18 carried by the ends of the springs 15 ride yieldingly and with la minimum amount of friction upon the side faces of the window posts 1, and thus the .ends of the curtain curtain can be raised or lowered with very little effort, and will remain at any elevation desired.

Should either end oi the curtain rod be elevated during the raising er lowering movement, the pins 20 carried by the plates or washers 19 will engage against the project ing portions of the molding 2 and the parting strip 4, and thus act as stops to prevent the ends of the springs 15 from being withdrawn from the curtain grooves.

The pins 11 can readily be screwed in and out of the ends of the tubular curtain rod 9, in order to increase or decrease the tension of the springs 15, and correspondingly increase or decrease the friction between the rollers 18 and the window posts 1.

In the modiloication shown in Figs. 4 and 5, pins 21 `are arranged 'to slide in the ends of the tubular rod 9, the said pins being normally `forced outward expansive coil springs 22, and carried by the outer ends of said pins 21 are the vertically disposed arms 23, on the ends of which are journaled antifriction rollers 24, which operate in the curtain grooves and bear against the Window posts.

Arranged to slide longitudinally in the outer ends of the pins 21 are plates 25, the outerends of which carry laterally projecting iingers 26, which occupy the branches 3 and 5 of the curtain grooves. These fingers 26 prevent the ends of the curtain rod from being accidentally disengaged from .the curtain grooves.

In the modified form of the curtain groove shown in Fig. 6, the groove .6 formed in the rear side of the molding 2 is dispensed with, and where this `form of curtain groove is made use of, but a single pair of plates or Washers 19 are located on each spring 15.

I claim l. The combination with car window posts, in the side faces of which are formed curtain grooves having restricted openings, of a curtain rod arranged on the curtain operating between the Window posts, resilient members arranged on the ends oi the curtain rod, anti-friction rollers carried by said resilient members and operated in the curtain grooves, and pivoted hooks carried by the ends of the resilient members and normally positioned in the wider portions oi' the curtain grooves for maintaining the curtain rod in proper position.

2. The combination with car window posts, in the side faces of which are formed curtain grooves having restricted openings, of a curtain rod arranged on the curtain o erating between the window posts, res ient members adjustably located on the rod, the ends of which resilient members are normally positioned in the wider portions of the curtain grooves, and pivoted hooks carried yby the ends oi' faces of which molding said resilient members and wider portions oi the grooves the withdrawal olI the ends oll from the curtain grooves.

3. The combination with car window posts, in the side i'aces oll which are formed curtain grooves having restricted openings, of a curtain rod arranged on the curtain operating between the window posts, pins adjustably arranged in each end oiI the curtain rod, sockets loosely mounted on the outer ends of the pins, springs integral with said sockets, the ends ol' which springs extend into the curtain grooves, rollers carried by the ends of the springs, and hooks pivotally arranged on the ends ol' the springs, and which hooks engage in the wider portions oi' the curtain grooves.

4. A curtain rod, comprising a body portion, resilient members arranged on the ends ol' said body portion, anti-friction rollers carried by said resilient members and which rollers operate in the curtain grooves, and pivoted hooks carried by the resilient members and occupying the curtain grooves for maintaining the curtain rod in operative position.
